Yeah, I trimed it all the way around so it would spin right and trimed the center and I did use the washer.
here's a picture of the top.

the mod look good ( if the zip ties was the way as i put mine it was better because the mesh can't play when it's spin)

i can't see good but if the mesh bigger then the wheel diameter it's also will not spin. (for me it's llok good but i am not sure).

how old is this impeller maybe the magnet is lose power to and it's hard to spin when the magnet not strong and lose power.
if i am not wrong melves have the ASM sedra pump and when he compare it to the ER sedra pump the result was different the ASM was more weak.

there is another way to try it :

you can start the pump of the water and see if it's spin and then lower the pump slow to the sump (be careful not to make splash around and put on it the elbow).

you can also take out the shaft and the washer and again start the pump of water and then close the cover (some time need to let it spin by finger)

at this way you can see the reading.

IMO this pump need to run on 14LPM with the mesh and 3 layer and after day or two it's need to increase more 2 LPM alone .

if you click on the link you can see wayne_sreef was able to get on his SD9000 with 3 layer 16-17lpm .

Thank you, so I can have it in a horizontal position instead of vertical.

Also I recently modded my G-5 and the problem I am having right now is that the outlet has to be above water level otherwise it wouldn't work right.

I had the outlet underwater a few times and it looked like the water inside the skimmer body dropped. Any suggestion ?

Thank you.

Also for the impeller modification, I noticed that you guys chop off the original impeller thingy and replaced it with the mesh. I was wondering would it make any different if I keep the original impeller ( without chopping off the thingy ) and just add the mesh and drill a few holes to tie the mesh down. Would this help ?

it will not work good at all (this was my first test before i chop the pins)

you can put the pump horizontal position but if you connect to it air flow meter and llok godd you going to see you lose air and it's not steady , vertical will pull more air and the impeller will spin more steady also the air.

try that on the H&S eheim pump , sedra 5000 and on the gen x 6000 . on all those pump the reading was higher and steady when the pump was vertical .

After the mod, did you guys get a lot of micro bubbles back to the tank?

 

[mfinn]

No, I have my sump setup so that I don't have that problem.

tee inside skimmer

tee inside skimmer

Just to let everyone know,
I have a g3 and the recirc with meshwheel and put a 1" tee on the top recirc tube inside the body.
way less turbulance and skimming.
I have super fine bubbles in the neck instead of large and fine mixed.

I don't suppose you have a flowmeter and got any readings before and after?

Contrary to popular belief, microbubbles are usually caused by the skimmer not drawing enough air (not too much). Basically, it moves to much water, and washed bubbles out the outpuy.

asm g3

asm g3

I don't get any micro bubbles through the output.
I feed the skimmer from tank drain at around 150 gph and that is not enough flow to force the bubbles out the bottom of the skimmer.All bubbles flow to the top.I can't see inside the skimmer at all,just a cloud of fine bubbles rising up.I don't have a air meter but the air hose is way louder than before

Could you post a pic or simple drawing of your T inside the body?

I actually just took it off and tried a 45* pvc facing upward.
Just experimenting but will let you guys know how it works.

question for you guys.
Anyone notice that after modding with recirc and meshwheel this thing puts out some foul smell.
My skimmer is pulling so much air that my room stinks.wifes mad,any suggestions???

 

[Charlie Davidson]

:lol2: Man, that means you have it working... its pulling out "crap" :thumbsup:
Add some kalk (or white viniger) to your collection cup... it will help big time

 

[jrmx635]

well I think the 45* facing up is working better than the tee.
I think I will try a 45 on the fitting from the tank drain and position that to blow upward to.
I will keep you guys posted.
Where do you guys find the best air/water level is in your skimmer?
I have tried all different levels but am getting impatient.
If I run the level so the bubbles break an inch before the top of the cup,it skims o.k. but very wet.
If I run the bubbles any lower it seems the skimmer isn't powerful enough to force the dry skimmate over the top.Even with all that extra air.
I admit tinkering with it is fun but this skimmer just doesn't compare to etss when it comes to skimming powwer.

I know I'm behind 5 pages, but here is the mesh wheel using the Quickie Scrub Pad from Lowes.

mod links?

mod links?

I was wondering if anyone has put together a list of mods for this skimmer? I think that it would take a year to get through all the posts on this unit to try and get all mods.
Thanks

G6 skimmer

G6 skimmer

Strange...I have no problems with the performance of my G6.
It consistently puts out brown smelly skimmate daily.

However, I am all ears when it comes to a cheap mod that will improve the skimmer .

Has anyone experimented with a "brush" wheel design or other similar materials?

I got the 3M material and a few other materials like the plastic scrubby pads. I also bought a few toothbrushes and some cleaning brushes and I plan to somehow cut these down with my dremel tool and fit them onto the needlewheel (with the pins cut).

I have a Dwyer meter and would also like to try the Enkamat material....anyone have any extra that I can buy?

 

[mikeatjac]

Has anyone mesh mod a 3500 on a G2 yet? I did and got a little impovement. Just checking to see the results of others.

 

[jjoos99]

I bought a used g3 that has the recir. mod using a sedra 5000 for both pumps. Should I do a mesh wheel on both impellers or just the recir pump?
Thanks
Jeff
